Patented June 27, 1933 v UNITED STATES PATENT OFFICE GEORGE GODDU, DECEASED, LATE OF WINCHESTER, MASSACHUSETTS, BY ISABELLE W. GODDU, EXECUTRIX, OF WINCHESTER, MASSACHUSETTS, ASSIGNOR TO UNITED SHOE MACHINERY CORPORATION, OF PATEIRSON, NEW JERSEY, A CORPORATION OF NEW JERSEY MACHINE FOR SHAPING UPPERS OVER LASTS Application filed May 31,

This invention relates to machines for use in the manufacture of shoes for shapinguppers over lasts. It is herein illustrated as applied to a lasting machine of the progressive type which operates successively on different portions of a shoe, and more particu larly to a machine constructed for the most part substantially as disclosed in-Letters Patout No. 1,7 96%51, granted on March 17, 1931 upon an application of George Goddu; but it is to be understood that in its more general aspects it is not thus limited in its applicability.

Machines of the character disclosed in the above-mentioned Letters Patent comprise in their organization a' gripper for pulling an upper over a last successively in different 10- cations along the edge of the last bottom, a device that is movable inwardly over the bottom of the last in time relation to each upper-pulling operation to lay the marginal portion of the upper over a sole having a lip thereon, and means for driving a staple from the overlaying device through the upper and the lip of the sole after each overlaying operation and for clinching the legs of the stapleon the inner face of the lip. The overlaying device, as therein disclosed, is movable inwardly over the sole in a direction somewhat inclined toward the bottom face of the last and is provided with a guideway from which the staple is driven through the upper and the lip in the same inclined direction.

The present invention, in one aspect, pro vides a novel construction such that the staple or other fastening used to fasten the upper to the lip of a sole in a machine for shaping uppers over lasts (for example, a machine of the above-mentionedcharacter) is driven in a direction at an angle to the direction of the inward movement of the overlaying device in laying the upper over the sole. As applied to an organization such as illustrated, in which the overlaying device is movable as above described ina direction inclined toward the bottom face of the last, the invention thus provides means whereby the fastening is drivenin a direction at a greater angle to the bottom face 1932. Serial No. 614,444.

of the last than the direction of the movement of the overlaying device. This is of particular advantage, for example, in operating on turn shoes to fasten the upper to the inwardly inclined inside channel lip of the sole, since the fastenings may be driven through the inclined lip in directions sub stantially perpendicular to the lip and clinched close to the base of the lip without the necessity of moving the overlaying device inwardly over the sole in adirection at a greater angle to the bottom of the last than is desirable for the bestresults in the overlaying operation. The invention is acshoes having shouldered insoles, or welt shoes having insoles of the more usual type in' case, for example, it is desired to clinch the faste nings very close to the base of the lip. It is further to be understood that the invention is not necessarily limited to an organization in which the overlaying device moves inwardly over the shoe bottom, as illustrated, in a direction inclined to the bot tom face of the last, nor to an organization in which the overlaying and fastening means operate in combination with a gripper that pulls the upper over the last. Furthermore, while the fastenings illustrated are staples, fastenings of other kinds may be utilized'con sistently with the objects of the invention. The novel features of the invention will now be more particularly described by reference to the accompanying drawings, and thereafter pointed out in the claims.

In the drawings,

I v I As more fully disclosed in thepreviously mentioned Letters Patent, the machine here in shown includes in its or anization a grip per comprising jaws 10 which are, operated to grip and pull the upper heightwise of the last and inwardly over the sole in different locations successively along the edge of the last bottom as the operator presents-and holds the shoe .in different positions for successive lasting operations, The shoe is supported against the pull of the gripper and is positioned in proper relation to the different operating instrumentalities by a sole rest member 12 which engages the sole onthe inner face of the lip a and-in operating on work of the typeillustrated extends into the inner channel adjacent tothe lip, this member being provided with clinching faces 14 (Fig. 6) for engaging the legs of the stapleand clinch-, ing them on the inner face of the lip. In theconstruction shown the member 12 is so shaped as to provide a comparatively thin lower edge portion to adaptit readily to eX- tend substantially to the bottom of the channel inthe sole and its clinchingfaces are arranged withreference to themore steeply inclined direction of drive of the staple (hereinafter more particularly referred to) to clinch the legs close to the base of the lip.

For laying the marginal portion of the upper inwardly over the sole'in time rela tion to each upper-pulling operation of the gripper there is providedan overlaying device comprising a staple-guiding nozzle 16' supported as described in thepreviously mentioned Letters Patent on a slide 18 which is movable along guideways 20 provided by a bracket 22fast on the head of the ma-' chine. These guideways are inclined in -such relation to the shoe positioned and'held as hereinab'ove described that the nozzle 16 engages the upperinitially a substantial distance 21bO"6 the sole and moves in a direction inclined toward the bottom face of the last in laying the upper inwardly over the sole and against the lip, the direction of the movement of the nozzle being indicated by the line b in Figs. 7 and 8. The nozzle 16 is provided with a guideway 24 for the staple 40 when .thejslide 18 is moved forwardly to cause the nozzle v16 to lay the upper over the sole, the latch being carried bya lever l2jwhich is operated after the forward movement of the slide 18 to cause a screw 4% on the slide to disconnect the latch from the arm 34: and thusrelease the arm to the action of the spring 38. Carried also by the slide 18 is an outside former comprising plates 46 which cooperate with a stationary inside former 48 to form .a staple in the forward movement of the slide, a member 50 being further provided to assist in forming the head of the staple against the inside former, as shown in Fig. 5. p The staple is thus formed in a location above the path of movement of the driver 30 and must accordingly be transferredto a position in alinement with the driver; For this purpose the plates 46, which have their inner faces recesses of less depth than the thickness of the staple wire and in' which the legs of the staple lie when they are formed, are carried .by a slide 52 which is movable downwardly at the end of the overlaying and staple forming operations to carry the staple to a position in which it rests on the guiding face 26, as illustrated in Fig. 4. It isatthis pointin the operation that the staple isdriven as hereinabove described. For a more complete understanding of the construction and manner of operation of the parts thus far described reference may be made. to the previously mentioned Letters Patent. I

For purposes'of the present invention the construction shown issuch that the face 26 of the member 28 for guiding the staple and the driver 30, and the alined guideway 24 of the nozzle 16, instead of being parallel to the direction of. movement of the slide 18'and of the nozzle in laying the upper over the sole as in the earlier construction, are inclined at a, greater angle to the bottomface of the last than the direction of such overlaying movement, the driver 30 ,also being inclined at the greater angle. This will be evident by reference to Figs. 7 and 8 where, as previously stated, the line Z2 indicates the direction of movement of the slide 18 and the nozzle 16.

.In operating on turn shoes, as illustrated,

this affords provisiorifor the driving of the staple through the inwardly inclined lip of the sole in a direction substantially perpendicular to the lip, and also for the clinching of the staple legs very close to the base of the lip by the member 12 specially constructed for this purpose, without the necessity of undesirably increasing the angle between the bottom face of the last and the direction of the overlaying movement of the nozzle 16, the best results being obtained in the overlaying operation from movement of this nozzle in a direction inclined at only a comparatively small angle to the bottom face of the last.

While the invention is thus illustrated and described with particular reference to the lasting of turn shoes, as affording very satisfactory means for lasting a shoe of that character, it will he understood that the construction disclosed may likewise be used with advantages in operating on shoes of other kinds, as hereinbefore suggested. The term sole as used in the claims is therefore'not to be construed as limited to the single sole of a turn shoe, but as applicable generally to that shoe bottom part over which an upper is lasted, including the insole of certain types of shoes,
